“Why?” said Dennis.

“Because you’ve prevented my doing them all day.”

Colin smiled to himself as he said that. It was most emphatically true: he would concentrate on his jobs to-night.

Violet went upstairs with Dennis at bed-time, relieved of her immediate fear, for Colin made no move to detain the boy, and whatever he had planned for himself, he did not look for Dennis’s partnership. Colin sat in his room when the others had gone up, and for half an hour, while he was waiting for midnight, he read and mused over the Memoirs of his ancestor. How symmetrical and consistent he had been till that senile ague of terror palsied him in the last year of his life! Never once in those fascinating pages was there a hint of any struggle in his soul, any stirrings of compassion or love which disturbed the poise of his undivided allegiance. Nor even at the end, did he waver in spirit, for it was easy to see that his belated pieties, his formal acts of pity and charity, sprang not from any turning of him in spirit towards God, but from the mere physical terror of his approaching doom. He only added cowardice, in fact, to his other sins, and went forth with a blacker load than ever.... So early, too, must he have initiated his two sons into the doctrines of the gospel, for long before the time came for their choice they were ripe and ready.

Colin dropped his reading. There was yet time to go upstairs and bid Dennis dress and come with him. But still the excuse held that the boy’s soul was not ready for the sacrament of evil: he had to learn the sweetness of evil for evil’s sake before he could take part in its worship. He would understand nothing: the rite would be meaningless, or, worse than that, would perhaps disgust and horrify him, and it was not in disgust and horror that he must be drawn, but must spring with a leap of the spirit towards a congenial mystery. And still Colin knew that all this was an excuse only: and his reason for not fetching the boy was that obstinate intruder in his own heart, which made him recoil from the notion of Dennis being frightened or revolted. It was, in fact, himself with whom he had to deal: he must cleanse his own heart of the tenderness which was in bud there, and by the inspiration of evil root out that alien weed. He must concentrate his mind on defiance and hate....

There came a tap at the door which led into the corridor up to the chapel. This was always kept locked, and the key to it, like a latch-key, he wore on his watch-chain. Otherwise the chapel could only be approached through Mr. Douglas’s lodging. He opened the door and found Vincenzo standing there.

“Pronto, signor,” said Vincenzo, and fell behind him as he walked up the corridor, leaving him at the door into the chapel, while he went through to the priest’s dwelling to vest himself as server. Colin entered: the chapel was redolent of stale incense, soon to be refreshed and renewed, and blazed with lights.

Presently the priest entered, served by Vincenzo. He was robed in that wonderful cope which, once stolen from some Italian sacristy, had been bought by Colin in Naples. For a minute or so, he knelt with his back to the altar and then, making the sign of the cross reversed, rose and began.

Though he knew the ritual well, Colin closely followed the service in the vellum-leaved book on his faldstool. Douglas had copied this in his exquisite formal handwriting from the missal of wondrous blasphemies, illuminating the initial letters with appropriate decoration and sacrilegious parodies of holy scenes. Two years had it taken him, a labour of love, and Colin, by keeping his attention on the book, strove to devote his mind to the spirit of the blasphemy. He confessed his fallings and his lapses from his vowed life, he tried to root Dennis out of his heart. He let his mind dwell on evil and cruelty and hate. And now the new clouds of incense rose from the censer that Vincenzo swung, the altar gleamed through the fragrant sanctification, and the supreme moment approached.

Colin felt the stir of the power seething round him, but he knew he no longer went out to meet it with welcome and heart’s surrender. All the pressure of his will was bent on doing so, but it was as if some grain of grit had got into the psychic mechanism of his soul: it checked and laboured, it did not respond with full smooth strokes. Why could he not be like Vincenzo who knelt there, his face working with some diabolical rapture? Vincenzo’s hands were clasped in front of him, his mouth grinned and slavered, he shook and swayed in that fierce gale of possession. The priest’s arms were raised now for consecration, and Vincenzo’s eyes were fixed on them; in a moment more, on the completion of the act, he would pull the rope of the bell that hung by him, and the three muffled strokes....
